13 Claims. (01. 155 181) 1. This invention relatesto. improvements in edge roll for use in upholstering parts such" asspring assemblies.

The main objects of'this invention'arez' First, to provide an edge roll for'upholstering spring assemblies and the like which may be" v quickly and easily applied thereto, is very securely mounted thereon and with the outer edge of the roll projecting substantially beyond the border of the spring assembly.

Second, to provide an edge roll having these advantages which maybe economically produced: in large quantities and maybe secured so asto provide a suitable edge support andforni for the upholstery and one which at thes'ame time-possesses substantial resilience. 7

Further objects relating to details and economies of the invention'willappear fromithe description to follow. The invention is pointed out in the claims.

A preferred embodiment of the inventionis illustrated in the accom'panying drawings, in which:

Fig. 1 is a fragmentary plan view of a spring assembly with the edge roll of my invention applied to one side or edge thereof.

Fig. 2 is an enlarged fragmentary View partially in section on a line'corresp'onding to'line' 22 of Fig. 1. v

Fig. 3 is a fragmentary view i gestion on a line corresponding to line 33o'f Fig. 2. a

. staple-like fasteners In the accompanying drawing I- have illustrated the edge roll of my invention as'applied to a cushion spring assembly comprising" upright coiled body springs I; a border framelwhich-is secured to the-top coils of outer bodys'pri-ngs'by'means of the clips 3, and tie w res a Which-aresecured to the inner portions of the topcoils-of the springs by means of the fasteners 5; This springassembly constitutes no part of myinvention except as my improved edge roll is associated therewith. I am employing the term edge roll-asthat is a commercial designatiori;

'My-improved edge roir qesignstea generally the numeral 6, comprises art elongated resilient core 1 of crumpledpaper, kr'aft"tissue crusl'1edand desirably twisted'b'eing'suitablei Around'this' I place a padding 8' of multiple sheet cellulosesometimes commercially esignated-as cellulose Wadding. The covering 9,' which-is desirably of burlap, completely embraces this resilient bodyportion and constitutes a flap.- The bodylportion is of inwardly tapered and'tgenerally pear shaped section. the enlarged: outeredge:|1| being trans versely curved, the curves merging into the sides 2, ofthe body as illustrated. A; row of; stitches l? secures the edges of the covering together providing-the flexible flap 1e.- W I I With the parts thus arranged tbe i'oll mainta-ins its shape and;presentsa'suitable softexterior whichis substantially resilient. In the preferred embodiment illustrated the roll is lp'roi vided with attaching-members [4 formed of bendable wire and having inturne'd hooks bat the outer endsthereof and bendable prongs I6 at their inner ends. These attaching members are provided with'upward onsets ll: adjacent their outerends, these offsets being eng-aged'by the IB which are inserted through the roll in spaced relation to its outer edge and in engagement with the core, padding and coverin thereof as is illustrated in the drawmg.

The fasteners H? are clinched at 19 011 the u per,

attaching members on the "under side of and in transverse relation to the roll. 7 v I V In applying the roll to a spring assembly, such as illustrated, the hooks l 5 are engaged with the,

border member 2 andthe prongs l6 engaged over a tie member andengaged with and desirably bent around the same thus'efiectively' securing the edge roll to the springassembly with the outer part of the edgeroll aboveand projecting outwardly beyond the border of the spring assembly. Commonly a covering 2| of burlap is arranged over the spring assembly as a preliminary step in upholstering the same, the covering depending-at the side of the spring assembly to provide a skirt portion 22 which is secured to the base frameof the assembly, not illustrated, the frame of achair or other part. not illustrated, to be upholstered. The upholstery padding is not illustrated but it may be arranged on the fabric 2| and the'upholstery covering-23 shown in'Fig, 2 arranged'over the padding an'dover the edge roll;

Structures embodying m invention maybe economically produced and very'quicklyand easily applied "to the part to be upholstered by relatively unskilled workmen. The edge roll is very effectively secured in position and in a mannerv to permit its functioning in. a most desirable manner. I have illustrated and described certain highly practical embodiments of my invention. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
